General Contracting

Comprehensive Project Delivery Managed from a Single Point

General contracting covers the integrated management of all construction activities, from planning and preparation to on-site execution, coordination of different disciplines, quality control, and final handover.

For residential, commercial, industrial, and various other types of projects, site organization, material procurement, construction works, subcontractor coordination, and implementation processes are managed in accordance with architectural, structural, mechanical, and electrical projects.

Each project is managed by evaluating its scope, budget, schedule, technical requirements, and site conditions together.

Depending on the scope of the project, the following services may be provided:

  • Project and needs analysis
  • Preparation of work schedules
  • Site organization
  • Subcontractor coordination
  • Material and procurement management
  • Structural construction works
  • Steel construction applications
  • Roofing and façade works
  • Mechanical works
  • Electrical works
  • Finishing works
  • Interior applications
  • Renovation and refurbishment
  • Industrial site works
  • Quality control
  • Occupational health and safety coordination
  • Preliminary and final acceptance processes
  • Turnkey applications

Advantages of General Contracting

Provides Single-Point Project Management

Different implementation teams and work packages are managed within a single planning system, allowing the project process to progress in a more controlled manner.

Strengthens Coordination Between Disciplines

Architectural, structural, mechanical, electrical, and other application teams are coordinated to help reduce conflicts on site.

Supports Controlled Schedule Management

Construction sequencing, material procurement, and team organization are planned to support progress in line with the agreed schedule.

Facilitates Cost Control

Planning work packages, material requirements, and construction methods at the beginning of the project contributes to more controlled budget management.

Organizes Site Operations

Working areas, team responsibilities, material deliveries, storage areas, and construction sequencing are planned systematically.

Strengthens Quality Control

Construction works are checked at defined stages for dimensions, materials, workmanship, and compliance with the project.

Simplifies the Process for the Client

Instead of managing multiple application teams separately, the project is coordinated through a single main contractor, helping simplify communication and project management.

General Contracting Services

Structural Construction Works

Foundations, reinforced concrete structural systems, walls, slabs, and main structural works are carried out in accordance with the project.

Steel Construction Applications

Steel structural systems, roofs, platforms, mezzanines, and project-specific steel solutions can be implemented.

Roofing and Façade Works

Roof systems, exterior façade applications, insulation, and external joinery are managed as part of the overall project.

Mechanical Installation Coordination

Heating, cooling, ventilation, plumbing, and other mechanical systems are coordinated in accordance with the relevant projects.

Electrical Works

General Contracting Process

Each project is planned individually according to its scope, site conditions, technical requirements, budget, and target completion date.

1. Project and Needs Analysis

The intended use of the project, scope of works, client expectations, and available technical documentation are reviewed.

2. Site Survey

Site conditions, existing buildings, access routes, material delivery areas, working zones, and technical limitations are examined.

3. Preparation of the Work Schedule

Work packages are identified, and construction sequencing, workforce requirements, and estimated durations are planned.

4. Budget and Resource Planning

Material, labor, equipment, and subcontractor requirements are evaluated and project resources are planned.

5. Site Organization

Site layout, working areas, team coordination, material storage, and site circulation are organized.

6. Structural Works

Foundations, reinforced concrete, steel structures, and main building works are carried out in accordance with technical projects.

7. Mechanical and Electrical Works

Infrastructure and installation works are coordinated with architectural and structural construction activities.

8. Roofing, Façade, and Finishing Works

The building envelope, interior applications, finishes, and complementary works are completed.

9. Quality and Implementation Controls

Construction works are inspected at defined stages according to the project, technical details, and application criteria.

10. Final Inspection and Handover

Completed works are reviewed, deficiencies within the project scope are corrected, and the building is handed over ready for use.

Subcontractor Management

In general contracting projects, certain work packages requiring specialist expertise may be carried out by subcontractors.

Their activities are planned according to the project schedule and coordinated with other teams.

Subcontractor management may include:

  • Defining the scope of work
  • Communicating technical requirements
  • Preparing work schedules
  • Planning site access
  • Coordinating work sequencing
  • Managing materials and equipment
  • Quality control
  • Occupational health and safety requirements
